Make sure you dont mess up any of the threads, I chewed one up pretty bad and had to use the stock manifold stud kinda like a tap to get the bolt in. I dont think it hurt anything but it scared the **** out of me when it happend. I had to take out all of the studs and use the supplied bolts by header which im not sure if they are grade 8 or not. The studs were not clearing the primary tubes. I heard the bassani gaskets are really good. As far as the egr I disconected it on the valve side first then connected it on the exhaust then back on the valve. It was a PITA. Also double check that all the bolts are tight, I had to do the job twice because of leaks.
